Title: Thin-film magnetic head and its production
Inventor: YAMAMOTO TAKAHIRO
IPC: G11B5/39
Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To improve the characteristics particularly when the frequency of recording information is high. SOLUTION: An induction type magnetic conversion element is provided with a nonmagnetic conductive member 15 so as to face at least part of an upper magnetic pole layer 14. Eddy current is, therefore, induced in the nonmagnetic conductive member 15 by recording current and the magnetic field leaking from the upper magnetic pole layer 14 is suppressed by the eddy current. In addition, the nonmagnetic conductive member 15 is in contact with the upper magnetic pole layer 14. The eddy current generated in the upper magnetic pole layer 14, therefore, flows to the nonmagnetic conductive member 15 as well.  As a result, the degradation in the intensity of the recording magnetic field by the eddy current, the increase in the delay of the recording magnetic field with respect to the recording current and the deterioration in the characteristics, such as the degradation in the time gradient of the rise of the recording magnetic field may be prevented.

Title: Quantitative measurement method of substance
Inventor: OOTSUCHI TETSUO
IPC: A61B6/00
Filed: 1991-10-04
Abstract: PURPOSE:To enable a plurality of substances to be determined by utilizing a negative value of a result which is obtained by calculation using the energy differential method and by determining the substances. CONSTITUTION:A waist part of a human body is constituted of three substances of bone 11, muscle 12, and fat 13. A transmission information of X rays is measured by a specific measurement system. For example, the measurement system is constituted of an X-rays source, an X-rays line sensor, and an operation device and a two-dimensional measurement can be made by scanning an X-rays line sensor in synchronization with the X-rays source. Then, after measurement, by analyzing a measurement result of the number of count of each part in each energy, it can be identified that fat 23 exists at a negative region after a differential calculation processing. In this manner, not only the bone 11 which is included in a human body but also fat 23 are detected simultaneously for enabling quantitative measurement to be executed.

Abstract: PROBLEM TO BE SOLVED: To improve the convenience of the portable telephone set by incorporating a transceiver type communication circuit and using the transceiver type communication circuit at the outside of a service area by a communication enterprise so as to attain communication between portable telephone sets. SOLUTION: A service area discrimination circuit 5 receives a radio wave sent from a communication enterprise and discriminates 'in-zone' when the electric field strength of the radio wave is a prescribed level or over, selects portable telephone set communication as a communication means, validates automatically a portable telephone set type communication circuit 6 to attain a communication function via a base station. In the case that the electric field strength of the received radio wave is not a prescribed level or over, the circuit 5 discriminates 'outside of zone', selects transceiver type communication as a communication means, validates automatically a transceiver type communication circuit 7 to select a communication function not via the base station.  In the case of portable telephone sets 3, 4 at the outside of the service area, since the transceiver communication circuit 7 is validated, mutual communication is attained by the transceiver communication system.

IPC: H04N5/95
Filed: 1989-10-02
Abstract: PURPOSE:To make a clock output stable just after a switching point by providing a PLL circuit, which is equipped with a phase comparing means, and a counter control circuit and controlling a feedback clock in the PLL circuit so as to be synchronized with a fluctuating synchronizing signal. CONSTITUTION:A switching pulse is inputted from an input terminal 15 to a counter control circuit 16 and a horizontal synchronizing signal is inputted form a synchronizing signal separator circuit 2 to the circuit 36. By these two signals, the horizontal synchronizing signal is detected before and after the switching point of a head and a control signal 17 is outputted so as to output the horizontal synchronizing signal before and after the switching point while synchronizing an N frequency dividing counter 8. Thus, even when the output period of the horizontal synchronizing signal is fluctuated at the switching point, the output of the above mentioned counter follows up this fluctuation. Thus, the output of a phase comparator circuit 25 is not rapidly changed at the switching point and the stable clock can be obtained.

IPC: G02F1/1333
Filed: 1990-09-27
Abstract: PURPOSE:To allow displaying with a high contrast on a low voltage by utilizing the different withstand voltage characteristics of a high-polymer binder dispersed with nematic liquid crystals exhibiting positive and negative dielectric anisotropies. CONSTITUTION:Specific graphic and character parts are formed of the high- polymer binder 100 dispersed with the nematic liquid crystals exhibiting, for example, the positive dielectric anisotropy in arbitrary shapes and the remaining parts are formed of the binder 101 having the negative dielectric anisotropy. These binders are clamped between electrodes 12 facing each other. The response of the binder part 100 exhibits a cloudy state unless a voltage is impressed thereto. The binder part turns transparent when the voltage is impressed. The response of the negative part 101 is likewise cloudy when the voltage is not impressed but the direction of directors 18 in droplets 16 parallel with the substrate plane and the cloudy degree is larger than the degree of the turbid state in the absence of the voltage impression when an AC voltage is impressed. Consequently, the same contrast as the combination of single kind is obtd. with the smaller thickness and, therefore, the operation on the low voltage is possible.

Filed: 1984-12-10
Abstract: PURPOSE:To make it possible to perform the automatic discrimination and judgment of a wheel, by providing a means for storing the presence information of the mark corresponding to a specific position on the basis of the output from a detection means. CONSTITUTION:A control apparatus CNT responds to the reception of a start signal INT to rotate a pulse motor M while out puts address signal A0, A1, A2 and sends out a writing signal WT to a decoder DEC at the point of time when a motor is stopped. A wheel PW is rotated by definite amount and the signal WT is outputted when the rotation of the wheel PW was stopped. The decoder DEC receives the output signals from the control apparatus CNT and a photosensor PS and selects any one of bits b0-b7 contained in a register REG on the basis of the informations of the address signals A0, A1, A2 to store the logical level ''0'' or ''1'' of the signal outputted from the sensor PS in synchronous relation to the signal WT at a selected bit position. By this method, the especial positional accurateness of the mark applied to the wheel is not required and hardware can be constituted inexpensively.
